United States Patent 3,036,548 SIZING ATTACHMENT FOR CLOTH CUTTINGMACHINES Lester J. Ulrich, Bufialo, N.Y., assignor to Eastman MachineCompany, Buffalo, N.Y. Filed Nov. 25, 1960, Ser. No. 71,490 4 Claims.((11. 118-38) This invention relates to motor driven cloth cuttingmachines provided with reciprocatory knives.

When cloth or other woven materials is cut, the cut edges of thematerial tend to ravel and stitching or binding of the same is generallynecessary before the material is sewn into a garment or other article toprevent ravelling. It is also possible to prevent ravelling by treatingthe seam with a suitable sizing material of a composition which does notwash out or become removed during dry cleaning. However, it is somewhattime-consuming to apply the sizing material by hand to the goods toprevent ravelling at the cut edges.

It is consequently an object of this invention to provide a cuttingmachine with means for applying a sizing liquid to the edges of aplurality of sheets of a lay of cloth at one time immediately aftercutting the same.

It is also an object of this invention to mount on the cutting machine acontainer for the sizing liquid and also a discharge device from whichthe sizing solution is discharged immediately after the knife has passedthrough the material.

In the accompanying drawings:

FIG. 1 is a front elevation of a cutting machine having applied theretoa sizing liquid-dispensing means embodying this invention.

FIG. 2 is a side elevation thereof.

FIG. 3 is a transverse, sectional plan view thereof on an enlarged scaleon line 33, FIG. 2.

FIG. 4 is a side elevation of the standard detached from the machine towhich my improvements are applied.

My improvements may be applied to any desired type of cloth cuttingmachine having a vertically reciprocating knife. The machine shown inthe drawings by way of example includes a base 7 formed to rest on andbe moved about on a table which supports the lay of material to be cut.This base, in the use of the machine, is moved underneath the material.

An upright standard 8 is rigidly secured to the base and extendsupwardly therefrom and supports the frame 9 of an electric motor 10which reciprocates the knife 11 in a vertical guide slot at the front ofthe standard 8. The standard may be secured to the base 7 in anysuitable manner. For example, the standard may be provided at its lowerend with an enlarged foot portion 12 which is rigidly secured to thebase 7 by a screw threaded connection, as shown in FIG. 4. The cuttingmachine is provided with the usual handles 13 and 14 by means of whichit is guided during its movement to effect cutting.

In order to apply the sizing solution correctly to the edges of thematerial of the lay immediately after it has been cut, I provide at therear end of the standard 8 a tube or pipe 15 rigidly secured to the rearof the standard. The tube, of course, is of materially smaller diameterthan the thickness or transverse dimension of the standard so as not tointerfere with a passage of the standard through the material after thesame has been cut. The lower end of this tube may be soldered orotherwise secured at 16 to a foot part 12 of the standard. The standard8 is preferably provided at its rear edge with a recess 24) into whichthe front portion of the tube 15 fits and the tube is securely held inthis recess in any suitable manner, for example, by providing the upperportion of the tube seams 21 of solder or the like which firmly connectsthe upper portion of that part of the tube which extends along the rearof the standard. The portion of the tube between the welds or solderedseams 21 and the connection 16 at the base of the standard is providedat opposite sides thereof with a large number of small openings 24through which the sizing solution is directed to the edges of thematerial which has been cut. By seating the tube within the recess inthe standard none of the material whihch has been cut will become lodgedin the space between the tube and the standard.

A sizing solution may be supplied to the distributing tube 15 in anysuitable manner, and in the construction shown by way of example, theupper end of the tube 15 may be bent to form an integral extension 25which connects wtih a suitable reservoir or tank 27 for the solution.This tank may be mounted on the cutting machine in any suitable ordesired manner, and in the construction shown the tank is shown assupported by means of a bracket 26 secured to the motor frame and to thetank. The tube 25 is provided with a valve 28 which may be opened atwill by the operator to admit sizing solution to the dispensing portion15 of the tube. This valve may be of any suitable or desired form whichcan be easily actuated by the operator. The valve 28 is connected bytubing 30 with the lower portion of the tank or reservoir 27.

In the use of my improvements, when the operator starts a cut, he opensthe valve 28 to admit sizing solution to the distributing pipe 15,whereupon he proceeds with the cutting in the usual manner. Aftercompleting a cut, he can close the valve 28. It will be noted that if itis desired to make cuts without applying a sizing material to the cutedges, it is merely necessary for the operator to keep the valve 28closed, since none of the sizing equipment interferes with the ordinaryuse of the machine.

By means of my improvements as deescribed, no separate operation forpreventing ravelling of the material is necessary since the spraying ofthe edges of the cotton fabric is effected simultaneously with thecutting of the same.

It will be understood that various changes in the details, materials andarrangements of parts which have been herein described and illustratedin order to explain the nature of the invention may be made by thoseskilled in the art Within the principle and scope of the invention asexpressed in the appended claims.
